'ions what@ plicd and C011H mHw). in ifs' ihm' through the filter, A #uppy pip@ V) wm ho, wmmcted with n summof supply n? qnid m' water under lOG chamber 8 through chambers 9, 10, 11 and 12. which is the diverting or final filtering chamber, it will rise in said chamber and pass into the intake 38 of a bypass pipe which is provided with a controlling valve 39 and which discharges, as at 40, into chamber 21. The water is forced through the earthen filter into the residue chamber '25, under pressure, from initial Supply 36. if it should be desired to draw ofi1 water which has passed through all of the filtering mediums, without waiting for its passage lthrough the. final filter 22,21. valved draw ofi conn xetion 41 may be provided to branch out from bypass pipe 38. To facilitate the proper supply through drawoff 41, valve 39 will be closed so that all of the Water entering bypass at 3S, from chamber 18, will fiow through drawoff 41. v In seme cases it will be desired to cleanse the filteringmaterials in the several chambers without actually removing and renewing the filtering` material. To provide for this operation, il connect the supply pipe 3G by a reverse pipe 42 which is provided with a valve 43. The reverse pipe 42 enters the bypass pipe so as to discharge through 38 into chamber 18. This flow into chamber 1S will be to the right of the figure and a suitable outlet will be provided, as' at 44, from chamber S. The outlet 44 is provided with a valve 45, which is normally closed but which isopen for return or washing action of the filtering material. Supply pipe EN', is provided with a valve 4G which will be closed when it is desired to send a supply of water through 4Q to chamber 18 for reverse or cleaning` action. Any suitable piping and valve connection ma)v be arranged from the pipe 3G to permit the supply of unfiltered water from this pipe and it will be understood that only that part of the water from the. supply pipe 8G which passes through the valve 4G will be filtered.

iVhilc l' have herein shown and described one specific form of my invention, it will be understood that slight changes might be Wihen the liquid gets into chamber 18,.

made in the `form and arrangement et the various parts of the structure without departing from the spirit and scope of my invention, and hence l, do not wish to be limited thereto except for such limitations as the claim may import.

In a filter of the character described, a horizontally arranged tank, a solid partition arranged within said tank substantially midway the ends thereof, a plurality of other partitions arranged in spaced reiation at one side of said first named partition, said last mentioned partitions being provided with staggered openings and forming a plurality of filter chambers, a fiuid inlet to one of' said filter chambers, a fluid outlet communicatingwith another of said chambers, another partition arranged in said tank in spaced relation to said first mentioned partition, said last mentioned partition having a central opening covered by a section of filtering material, pipes connecting said fluid outlet from one of said first mentioned chambers, with the chamber :formed between said first and last mentioned partitions, another partition arranged in. said tank in .spaced relation to said Yfirst mentioned partition to form a settling chamber, the last mentioned partition having an opening in eiose proximity to its upper edge to permit the surface fluid in the settling chamber to flow to the chamber beyond said last mentioned. partition. a storage. chamber formed between said last mentioned partition and the adjacent end of said tank, means to withdraw the fi uid from said storage chamber`v and said tank being cut away adjacent said settling chamber whereby access may be had to said chamber `for cleaning purposes, and means to close said cut away portion, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
